How long does it take the moon to return the the same spot in the sky?
The time it takes for the Moon to return to the same spot in the sky, known as a lunar sidereal month, is about 27.3 days. This period is based on the Moon's orbit around the Earth with respect to the stars.
How can you tell a satellite is in geostationary orbit?
A satellite is in geostationary orbit when it orbits the Earth at the same speed and direction as the Earth's rotation. This allows the satellite to appear stationary from the surface of the Earth. Measurements of its position and velocity can confirm that it is in geostationary orbit.
Does the International Space Station have to orbit earth or can it be placed in space as a refuel spot so manned space travel can go further searching other planets?
If it remains aloft, it is in orbit. There are many different types of orbit. For instance, a geostationary orbit keeps the orbiting body positioned over the same spot on Earth. However an apparent retrograde orbit moves the satellite in the opposite direction of the Earth's rotation, and a Polar orbit sends the satellite over both poles, or nearly so.
What advantages does a weather satellite in geostationary orbit have over a weather satellite in polar orbit?
A satellite in Geosychronous Earth Orbit (GEO) orbits the Earth in the same time period that the Earth spins, so the satellite appears to be stationary over one spot above the Earth's equator. It's always looking down at the same area of the Earth. A satellite in a polar orbit will pass quickly over any one spot on Earth and keep going. It can't watch the same area for a long period. Depending on the altitude of the orbit, it may take days or weeks to pass over the same area again. However, polar orbits are typically much lower, permitting a much higher resolution image. This is very important for photo imagery, but not so much for weather.
What day does the moon orbit the earth?
The moon is in motion in its orbital path 24/7/365. At any moment, it's at the same spot, relative to the earth, that it occupied 27.32 days earlier.
What term is given to satellites that remain above the same point on the Earth's surface in their orbit?
There are two types of satellites that are located in a foxed spot over earth the first is reconnaissance satellites for observation of earth and usually used by the military.. The second is earth observation satellites and are intended for environmental monitoring
What satellite whose orbit is synchronized with the rotation of the earth?
Its called a geostationary satellite. Its quite far out, meaning its 24 hour orbit is quite long when compared with satellites closer in to earth. Is appears stationary in our skies, in the same spot throughout its orbit. This makes it a lot easier to track, a fixed dish can be used.
What is the length of one solar day on the moon?
The length of day on moon is (27.32 EARTH DAYS)27.32 days is the length of a sidereal day.The length of a lunar solar day (the time it takes the sun to appear in the same spot overhead) is 29.5 days. This is because as the moon turns, it also travels along its orbit about the sun.
Can show us a diagram of the moon sun and earth orbit?
Draw a diagram using compasses. The Sun is at the centre and the Earth's orbit could have a radius of 4 inches. Put a spot somewhere on the orbit to represent the Earth. Then the Moon's orbit is a small circle round the Earth with a radius of 1/100 inch, about the size of a full stop.
What are geostationary orbits?
an orbit that is about 36000km above the Earth's surface and in which a satellite is above a fixed spot on the equator.
If you can see the International Space Station on one orbit why can't you see it on the next one 90 minutes later?
The earth is rotating under the space station's orbit, at roughly 1000 mph (at the equator). In 90 minutes, when the ISS is in the same spot in its orbit, you will have moved about 1500 miles westward.
What are the advantages and disadvantages of satellites?
At 35,786km is a special orbit for Geo-stationary satellites. Since they orbit the earth in the same time that it takes the earth to spin once on its axis, it means that the satellite can stay in roughly the same spot over the earth. The main advantage is that they appear to stay in the same spot in the sky, meaning that satellite dishes can be fixed onto them, rather than having to track them accross the sky. Their orbit is quite high, so they do not experience as much atmospheric drag - their orbits may be a lot more stable. The main disadvantage is that it takes more energy to get them to this height, so more fuel is needed. Another disadvantage of this special orbit, is that their may be loads of satellites, so the chances of a collision are increased.
